ASTM F2080-15

1.1 This specification covers cold-expansion fittings using metal compression-sleeves for use with cross-linked polyethylene (PEX) plastic pipe in ³/₈-in., ¹/₂-in., ⁵/₈-in., ³/₄-in., 1-in., 1¹/₄-in., 1¹/₂-in., and 2 in. nominal diameters, whereby the PEX pipe is cold-expanded before fitting assembly. These cold-expansion fittings and metal compression-sleeves are intended for use in residential and commercial, hot and cold, potable water distribution systems, as well as sealed central heating, including under-floor heating systems, with continuous operation at pressures up to and including 100 psi (690 kPa), and at temperatures up to and including 180°F (82°C).
